Garmin Optimizes GTN Series for Helicopter Operators

By Frank Lombardi

The GTN series of GPS Nav/Comm, Garmin’s successor to the popular GNS 430 and 530 GPS Nav/Comm systems, made its debut in March of 2011. Featuring a touchscreen interface and multifunction display (MFD), it is continuing to gain popularity in the fixed-wing community. This year, Garmin announces its optimization for helicopter operations. The GTN series has an already impressive suite of multifunction display features including the ability to access traffic info, datalinked weather or weather radar. As an option, it can control a remote-mounted transponder and audio processor as well.

The helicopter version of the GTN series will have hardware enhanced to meet more stringent helicopter vibration and temperature requirements. Software modifications will include provisions for Helicopter terrain awareness and warning system (HTAWS) with exceptional terrain resolution, and optional night vision goggle compatibility.

If integrating a GMA 35 audio processor into the system, helicopter operators can take advantage of Garmin’s “Telligence” voice command technology, allowing pilots to keep their hands on the controls.

In lieu of using voice commands, and to more accurately use the touchscreen, Garmin thoughtfully designed an ergonomic shelf on the bezel to help with finger placement. For those who are not yet ready for full touchscreen operation, the GTN units have a set of multipurpose knobs to dial in frequencies, codes, or numerical data.
